Find a switched +12v source in the factory fuse box. What vehicle are you installing the Tube in?

I am not an electrical wizzard. Hooked up the FAST, ran power to the 10100 from the battery, and found a ground. Had no idea where to hook up the blue/white wire, so I left it unconnected. I am getting no power to the Zook. Do I need to have the blue/white connected to a 12v source to get power to the Zook?
Incidentally, the directions call for hooking up the solid green wire and a green striped wire. No green wires on my harness. Gray, gray striped, white, and black/white wires.
Thanks
